采用两步法合成了SnO 2-ZnO核壳结构纳米纤维。首先，通过静电纺丝法合成SnO 2纳米纤维。在序列中，ZnO壳层沉积使用原子层沉积在静电纺丝合成的SnO 2纳米纤维。为了证明合成的核壳纳米纤维的实际应用，我们研究了它们对O-2和NO2的传感性能。在这些传感器中观察到的高灵敏度和动态可重复性表明，核壳纳米纤维是有前途的灵敏和可靠的化学传感器。
SnO2-ZnO core-shell nanofibers were synthesized via a novel two-step process. First, SnO2 nanofibers were synthesized by electrospinning. In sequence, ZnO shell layers were deposited using atomic layer deposition on the electrospinning synthesized SnO2 nanofibers. To demonstrate the practical applications of the synthesized core-shell nanofibers, we investigated their sensing properties to O-2 and NO2. The high sensitivity and dynamic repeatability observed in these sensors reveal that the core-shell nanofibers are promising as sensitive and reliable chemical sensors.
